i see we both agreed that +500 for extra 2 cores is way too much.
configurability is the thing i like, regardless of the manufacturer or prices.
but, you are kinda wrong about sweet spot and diminishing returns :)
it was true, just a couple of years ago. 7nm zen 2 has changed everything, because now you can put neary infinite number of cores in the same tdp/socket, and there is no so desirable early "a bit extra", always overkill for you needs. 16 is too much for desktop, 64 is too much for hedt. look at the prices for exrta cores..they are nearly linear. now zen 2 brings something similar in laptops. 6 cores->8 cores is just 100 dollars/euro more.
Yes, I certainly wouldn't pay it unless I was desperate for the extra performance (and, apparently, couldn't go to competition).
Even if price per core scales nicely (and IIRC local prices, it doesn't always - I recall the 3950 being an outlier compared to both 8 and 12 core units), performance gains are not that cooperative. It depends on the workload and cost equation will depend on the rest of the computer. To some extent, AMD is just being nice as they're penetrating the market (fighting an uphill battle). Yes, the chiplet approach has undisputed advantages. And Intel had plenty of time to gradually inflate prices. Essentially, it's another level of clustering. Instead of having multiple sockets, you have multiple chiplets.
Of course you really can't, even putting aside the "nearly infinite". Because each core needs power and data. Divide and conquer. It's just simpler to design a 4 core chip than 16 core (not to mention 64 core). And defects in manufacture are cheaper (you discard just 4 cores rather than 16).
As I wrote, IIRC Apple is also asking just 100. It's really weird. :-) Then again, the 10 Gb Ethernet option for Mac Mini is also a decent deal considering the prices of cards. It's the RAM and storage where they go completely crazy. Funnily enough, in the MBP 16, the price for RAM (per GB) is the same as VRAM IIRC.
It's a shame they went with a 16:9 display. The Intel based Swift 3 has 3:2 (and Acer has some other 3:2 devices). I hate 16:9, especially on small screens. This farce, I mean trend, has to die. Yesterday was too late. Then they can give us, perhaps, some proper cursor keys. Yay. :-)
